RELAX!
Breeza..relax...the medical is very simple and if you are healthy you will pass easily. They tell you on the day if you pass.
The hearing test is soooooo funny. They put you in headphones and ask you to press a button as soon as you hear a BEEEEEEP...It starts loud and then gets soooo soft you can't even hear it (I was like...was that a beep or am I just thinking I heard it...ha ha)....I'm 100% sure I pressed the button when there was NO beep but the test lasts for ages and they must re-test you on the ones you miss....and as you get the hang of it I found I got better at it.
So Breeza...trust the Chicken....you will be fine....Good Luck!
